Myelin sheaths in the central nervous system can withstand damage and dynamically remodel
Myelin damage is a hallmark of several neurological disorders, but how it occurs remains to be fully understood. In this study, we found that early damage in zebrafish and rodent demyelination models ...

First joint work between @jameslightfoot.bsky.social and my lab is now published! Machine-learning, aggression, genetics, beautiful fluorescent transgenics and evolution! You can find it all!
Why do some worms graze on bacteria while others hunt and kill?
Our study, published today in Nature, reveals how predatory aggression evolved in nematodes.
Led by @gunizgozeeren.bsky.social and @leoboeger.bsky.social across the @jameslightfoot.bsky.social and @monikakscholz.bsky.social labs.

The second paper from the lab is now available on bioRxiv: www.biorxiv.org/content/10.6...
We discovered that cannibalistic behavior in fly larvae is social-context dependent. Larval groups avoid dead conspecifics; individuals show high attraction. They only do it when no one is watching 😉
